摘　　要：由于在评估前未对各项指标数据进行处理,导致网络安全态势量化评估所得结果存在的评价精度低和评价结果应用价值低的问题,对光纤光栅传感网络安全态势量化评估方法进行优化设计。结合网络的拓扑结果和传感运行原理构建对应的光纤光栅传感网络,利用传感器设备感知实时产生的网络数据。通过分析网络安全属性,构建网络安全态势量化评估的指标体系,并采用模糊层次分析法对各个指标进行量化。然后设置网络的安全态势等级标准,并对感知网络安全态势指标定量数据进行处理,以免陷于极端情况,确保指标量化的准确性,以提高评估结果的精度,实现对光纤光栅传感网络安全态势的评估。通过与传统评估方法的对比实验得出结论:设计的评估方法得出的评估结果更加接近设置的网络安全态势数据,且通过设计评估方法的应用能够有效地降低网络故障的发生,具有较高的应用价值。Due to the processing of various data before the evaluation,there are problems with low evaluation accuracy and low application value of the results obtained from the quantitative evaluation of network security situation.Therefore,the optimization de-sign of the fiber optic grating sensing network security situation quantitative evaluation method is carried out.Construct a correspond-ing fiber optic grating sensing network based on the topology results of the network and the sensing operation principle,and use sensor devices to perceive real-time network data generated.By analyzing network security attributes,a quantitative evaluation index system for network security situation is constructed,and fuzzy analytic hierarchy process is used to quantify each indicator.Then set the secu-rity situation level standards for the network,and process the quantitative data of perceived network security situation indicators to a-void falling into extreme situations,ensure the accuracy of indicator quantification,improve the accuracy of evaluation results,and a-chieve the evaluation of the security situation of fiber optic grating sensing networks.Through comparative experiments with traditional evaluation methods,it is concluded that the evaluation results obtained by the designed evaluation method are closer to the set network security situation data,and the application of the design evaluation method can effectively reduce the occurrence of network failures,which has high application value.
